Morphological meniscus changes measured by WORMS scoring between two time-points (in years). Percentage of subjects, which show an increase in the entire meniscus grading for the overlying meniscus above the cartilage repair region or the cartilage defect region, respectively. In controls without cartilage defect any increase of either meniscus was considered as progression.
